I agree. Passing parameters via SO API and using VID UI to input these 
parameters would be satisfying enough.

According to adding new BPMN workflows, I believe workflow designer is what 
will be used for that. https://wiki.onap.org/display/DW/Workflow+Designer

Subject: RE: [E] [onap-discuss] Why we need manual SDN-C preloading?



Hi



Preload is about providing some Heat parameters value at instantiation time. 
Without preload, your Heat stack will use default values from your Heat 
templates coming from SDC (after distribution).

For example, “image name” or “flavor name” are not the same from one VIM to 
another VIM.



You are right, the way it works today in Beijing is not satisfying.



My proposal would be to replace that SDNC preload by the possibility to provide 
parameters/values via SO API and to use a BPMN that would use those 
parameters/values.



That means to be able to define and add a new BPMN (I do not know how to do 
that)



If anyone can share the procedure to add a new BPMN, we could try work on it.



Regards



René

I second this comment. We are also having same question and infact we even 
tried to bypass this SDN-C preload check but not successful so far. We modified 
BPMN file to skip the SDN-C interaction altogether, however SO's state is still 
stuck in "In Progess" state.



IMHO SDN-C preload is optional step, shouldn't be introduced as a mandatory 
step in BPMN. There were lots of usecase specific work done in R1, primarily to 
just demo a particular usecase. However this is not changed even after moving 
to 2 releases.

   Hello,

   As in title, why we need manual SDN-C preloading in ONAP? We use and work 
with ONAP from Amsterdam release. It was surprising for us that there are some 
additional, manual steps needed to perform orchestration for any single VNF. We 
have currently ongoing development of Casablanca release and I don’t see the 
feature requests to automate SDN-C preloading in ONAP. In my opinion it’s just 
a matter of information exchange between SDC/SO/AAI/SDN-C.

   Could you explain me why this manual step is still needed for ONAP? Is there 
any plan to automate it?

   Regards,
   Tomek
